Description

  The present invention relates to a hermetic container and a hermetic container set suitable for taking out an object to be packaged stored in a clean state in a clean state.

  In medical examinations, diagnoses and treatments, it is important that the equipment and pharmaceuticals used are not contaminated. For example, the micropipette tip used in the test is sealed with a film in a clean and uncontaminated state (for example, an endotoxin-free state) in order to prevent contamination by endotoxin (endotoxin) and the like. Individually contained in a separate container. The chip is taken out by tearing the film at the time of use.

  As a container sealed with a film, for example, a sealed container shown in FIGS. 1A and 1B is known. The sealed container 10 includes a container having a recess 11 and a flange 12 formed around the opening thereof, and a film 14 that is in close contact with the flange 12 and seals the opening of the recess 11. The film 14 has a knob 15 formed on the collar portion 12 by cutting. The knob 15 is formed by cutting off three sides excluding the concave portion 11 side, and is not in close contact with the collar portion 12. Therefore, by pulling the knob 15 toward the recess 11, the film 14 is broken up to the top of the recess 11 as shown in FIG. 1B. Thus, the concave portion 11 is opened, and the article to be packaged stored in the concave portion 11 is taken out (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2005-015002

  When the sealed container 10 is applied to the tip container, for example, the tip is taken out by inserting the tip of the micropipette body (pipetter) into the recess 11 from the tear of the film 14 and This is done by attaching a tip to the tip and pulling out the pipettor from the recess 11. However, in the sealed container 10, the width of the knob 15 is narrower than the width of the recess 11, and thus the width of the portion of the film 14 that is torn off is narrower than the width of the recess 11. Moreover, although the inside of the recessed part 11 and the inner surface of the film 14 are normally maintained in a clean state, the outer surface of the film 14 may be contaminated.

  For this reason, even if the inside of the sealed container 10 is kept endotoxin-free, when the micropipette is pulled out from the recess 11, the tip is contaminated with endotoxin by contacting the outer surface of the film 14. Sometimes. Further, when the film 14 is torn off on the opening of the concave portion 11, the contamination source adhering to the outer surface of the film 14 may enter the sealed container 10 and contaminate the chip.

  This invention makes it the 1st subject to provide the airtight container which can take out the to-be packaged object accommodated in the container in the clean state from a container in the clean state.

  Moreover, this invention makes it a 2nd subject to provide the airtight container set convenient for taking out from the container of the said to-be packaged object in a clean state.

  The present invention provides a multi-chamber container in which a plurality of containers having openings are arranged so that the openings are arranged in a line in a first direction, and the multi-chamber container bonded to the multi-chamber container A closed film that seals all the openings of the container, the film extending further outward in the first direction than the opening at the end of the multi-chamber container.

The film 220 is bonded to the end surface on the opening 211 side of the multi-chamber container 210 (FIGS. 3B and 4A). As long as the container 2100 can be sealed, the film 220 may be bonded to the entire end face or may be bonded to a part thereof.

  The multi-chamber container 210 includes eight containers 2100 arranged in a line in the X direction (FIG. 4A). The container 2100 has an opening 211. In the multi-chamber container 210, the containers 2100 are arranged so that the openings 211 are arranged in a line in the X direction.

  The container 2100 is an elongated bottomed container whose depth direction is the Z direction orthogonal to the X direction. Each container 2100 accommodates a micropipette tip 230. The chip 230 is accommodated in each of the containers 2100 in a clean state free of endotoxin, for example.

  The shape of the opening 211 can be set according to the shape of the object to be accommodated in the container 2100. For example, if the object is the chip 230, the maximum diameter portion of the chip 230 can pass through. It may be any shape and may be circular. The multi-chamber container 210 further has a ridge 212 protruding toward the film 220 in the Z direction around the opening 211 (FIG. 4B). The shape of the protrusion 212 in the plan view (the shape of the protrusion 212 projected onto the XY plane) is an annular shape, similar to the shape of the opening 211. The protrusion length (h in FIG. 4B) of the protrusion 212 in the Z direction is, for example, 0.5 mm.

  The multi-chamber container 210 further has a breakable thin portion 240 that connects containers 2100 adjacent in the X direction (FIG. 4B). The thin portion 240 is a portion between the outer peripheral walls of the adjacent containers 2100, the length of the thin portion 240 in the Z direction is 5.0 mm, and the length of the thin portion 240 in the Y direction orthogonal to the X direction and the Z direction. The thickness (width) is 0.5 mm, and the length (thickness) of the thin portion 240 in the X direction is 0.5 mm.

  The multi-chamber container 210 further includes locking portions 250 arranged at both ends of the multi-chamber container 210 (FIG. 4A). The locking portion 250 includes a protruding portion 251 that protrudes further outward along the X direction from the end of the multi-chamber container 210, and a bar 252 that extends from the protruding portion 251 along the Z direction to the opposite side of the film 220. Have.

  The multi-chamber container 210 is obtained by, for example, resin injection molding. Examples of the types of resins include polyolefin resins, polyamide resins, polystyrene resins, polymethyl methacrylate resins, polycarbonates, and cycloolefin copolymer resins. Examples of the polyolefin resin include polypropylene resins such as homopolypropylene, random polypropylene and block polypropylene; and polyethylene resins such as high density polyethylene and low density polyethylene. Examples of the polyamide-based resin include nylon. Examples of the polystyrene-based resin include polystyrene that may contain a rubber component for reinforcement.

  FIG. 5A is a plan view of the film 220, and FIG. 5B is an enlarged view of a part of the film 220.

  The film 220 includes eight lid portions 221 arranged in a row in the X direction, first tabs 222 extending in the X direction from the lid portions 221 at both ends in the X direction, and each lid portion 221 extends in the Y direction. And a break line 224 that is a boundary line between the lid portions 221 adjacent to each other in the X direction.

  Each of the lid portions 221 is formed by parting the film 220 by a break line 224 so as to close each of the openings 211 when the film 220 is bonded to the multi-chamber container 210.

  As shown in FIG. 4B, the lid 221 adheres to the peripheral edge of the opening 211 in the multi-chamber container 210 and seals the opening 211. The lid portion 221 is bonded to the entire surface of the ridge 212 so as to cover the ridge 212. Although it is preferable that the cover 221 is bonded to the entire surface of the protrusion 212 from the viewpoint of bonding the cover 221 (film 220) to the multi-chamber container 210 with sufficient strength, the container 2100 is sealed. In addition, the lid 221 may be bonded to a part of the surface of the ridge 212 within a range where sufficient adhesive strength is obtained.

  The first tab 222 is disposed at a position overlapping the protrusion 251 in the Z direction, but is not bonded to the protrusion 251. That is, the first tab 222 is a first free end that extends further outward from the opening 211 at the end in the X direction. For example, the planar shape of the first tab 222 is a rectangle, the length of the first tab 222 in the X direction is 8.0 mm, and the length (width) of the first tab 222 in the Y direction is 8. 0 mm.

  The second tab 223 is disposed further outward in the Y direction from the end surface on the opening 211 side of the multi-chamber container 210. The second tab 223 does not overlap the multi-chamber container 210 in the Z direction and is not bonded to the multi-chamber container 210. That is, the second tab 223 is a second free end that extends further outward in the Y direction than the respective openings 211. For example, the planar shape of the second tab 223 is a rectangle, the length of the second tab 223 in the Y direction is 8.0 mm, and the length (width) of the second tab 223 in the X direction is 8. 0 mm.

  The breaking line 224 is located between the adjacent openings 211 in the X direction, as shown in FIG. 4B. The break line 224 is formed along the direction crossing the X direction. For example, in the present embodiment, the break line 224 is formed along the Y direction. The breaking line 224 is a line for breaking the film 220 along the Y direction when the second tab 223 is pulled. That is, the direction in which the breaking line 224 extends is the same as the direction in which the second tab 223 extends.

  Break line 224 includes a slit 225 and a non-penetrating portion 226. The slit 225 is formed along the direction crossing the X direction (Y direction in the present embodiment) and penetrates the film 220. The non-penetrating portion 226 is adjacent to the slit 225 in the Y direction. The non-penetrating portion 226 is a portion that does not penetrate the film 220 and is a portion in which the film 220 continues in the X direction.

  Three places of the both ends in the Y direction of the breaking line 224 and the center part are comprised by the slit 225, and the slit 225 in the breaking line 224 is comprised by the two non-penetrating parts 226. As described above, the end of the breaking line 224 on the second tab 223 side is constituted by the slit 225. The length of each non-penetrating portion 226 in the Y direction is, for example, 0.5 mm.

  The film 220 is obtained, for example, by cutting a resin film. Examples of the type of the resin include polyester resin, polyolefin resin, polyamide resin, polycarbonate, ethylene copolymer, and combinations thereof. Examples of the polyester resin include polyethylene terephthalate and polyethylene naphthalate. Examples of the polyolefin resin include high density polypropylene, low density polyethylene, linear low density ethylene-α-olefin copolymer, homopolypropylene, and random copolymer polypropylene using ethylene and propylene as monomers. The ethylene copolymer is a copolymer of ethylene and (meth) acrylic acid alkyl ester or vinyl ester. The film 220 may contain a material other than resin as long as the film 220 appropriately functions as a laminate of a metal foil and a resin film.

  The film 220 can be adhered to the end surface on the opening 211 side of the multi-chamber container 210 by, for example, heat sealing. When the film 220 is heat-sealed, for example, the film 220 is pressed against the multi-chamber container 210 with an appropriate force with an elastic body made of silicone rubber, for example, so that the film 220 is in close contact with the peripheral wall surface of the protrusion 212. Can be bonded to the multi-chamber container 210.

  As shown in FIGS. 2, 3A, and 3B, the support frame 300 is a frame having a rectangular shape when viewed from the Z direction. The support frame 300 has twelve holes 310 on one end surface in the Z direction of each of the pair of long sides along the Y direction. The hole 310 is sized to accommodate the bar 252. The material of the support frame 300 is not particularly limited. The support frame 300 can be obtained, for example, by resin molding. Examples of the type of the resin include polyolefin resin, polyamide resin, polystyrene resin, polymethyl methacrylate resin, polycarbonate, and cycloolefin copolymer resin.

(Function)
When the first tab 222 is pulled along the X direction, the film 220 continues in the X direction at the non-penetrating portion 226, and thus peels off from the end face of the multi-chamber container 210 without breaking. Therefore, all the eight openings 211 of the sealed container 200 are completely opened.

  When the second tab 223 is pulled along the Y direction, the lid portion 221 is peeled off from the end surface of the multi-chamber container 210 along the slit 225, and the non-penetrating portion 226 is easily broken. Breaks. Therefore, only the lid portion 221 to which the second tab 223 is connected is peeled from the multi-chamber container 210, and only one opening portion 211 corresponding to the lid portion 221 is completely opened.

  Further, if the thin portion 240 is broken, the film 220 is torn at a breaking line 224 located immediately above the thin portion 240, and therefore, individual sealing in which one container 2100 is sealed by one lid portion 221 having the second tab 223. A container is obtained.

  Further, the rods 252 of the locking portions 250 at both ends of the hermetic container 200 are inserted into the pair of holes 310 at the opposing positions arranged in the pair of long side portions of the support frame 300. By the insertion, the locking part 250 is detachably locked to the support frame 300, and the sealed container 200 is supported by the support frame 300 with the opening 211 facing one side in the Z direction.

  For example, the distance between the centers of the openings 211 in the X direction is set to 9 mm, and the distance between the centers of the holes 310 in the Y direction of the support frame 300 is set to 9 mm. When 200 is supported, the positions of the openings 211 of the 12 sealed containers 200 supported by the support frame 300 are the same as the arrangement of the wells in the 96-well microplate.

  The chip 230 is taken out as follows, for example. First, the tip of the pipettor is inserted into the container 2100 from the opening 211. Next, the tip 230 is attached to the tip of the pipetter in the container 2100, and the pipetter is pulled out from the container 2100. Thus, a micropipette is constructed.

  Since the film 220 is completely removed from the opening 211, the chip 230 does not touch the film 220 when being pulled out of the container 2100. The chip 230 is taken out from the container 2100 in a usable state. Therefore, contamination due to the mounting of the chip 230 does not occur. Thus, the chip 230 is removed from the container 2100 and used in a clean state free of endotoxins.

  Since the closed container 200 is supported by the support frame 300, when all of the eight series of containers 2100 are opened and the eight series of pipettors are inserted, the tip is placed on all of the tips of the eight series of pipettors as described above. 230 is mounted.

(effect)
The sealed container set 100 includes the sealed container 200 and the support frame 300 as described above. Therefore, since the sealed container 200 can be handled with the opening 211 of the container 210 facing upward, it is convenient for taking out the chip 230 from the container 2100 in a clean state.

  As described above, the sealed container 200 includes the multi-chamber container 210 and the single film 220 that adheres to the multi-chamber container 210 and seals all the openings 211 of the multi-chamber container 210. Each of the individual containers 2100 in the multi-chamber container 210 contains the chip 230, and the film 220 extends further outward in the X direction than the opening 210 at the end of the multi-chamber container 210. Arranged between the tab 222, the plurality of second tabs 223 extending further outward in the Y direction than each of the openings 211, and the adjacent opening 211 in the X direction, the film 220 is broken along the Y direction. Breaking line 224 for the Accordingly, the eight containers 2100 or one container 2100 can be completely opened by pulling the first tab 222 or the second tab 223 in the X direction or the Y direction. Therefore, according to the airtight container 200, the chip | tip 230 accommodated in the container 2100 in the clean state can be taken out from the container 2100 in the clean state.

  Further, according to the sealed container 200, the container 2100 is opened by complete peeling of the lid 221 from the multi-chamber container 210, so that the film 220 is not torn off on the opening 211 of the container 2100. . For this reason, according to the airtight container 200, the possibility that the contamination source adhering to the outer surface of the film 220 enters the inside of the container 2100 can significantly reduce the possibility that the chip 230 and the inside of the container 2100 are contaminated. .

  Note that the inside of the container 2100 is clean even after the chip 230 is taken out. Therefore, the container 2100 after the chip 230 is taken out can be used as a clean container or a clean instrument.

  Moreover, it is much more effective from the viewpoint of making it possible to individually use the eight sealed containers, in which the multi-chamber container 210 further has a breakable thin portion 240 that connects the adjacent containers 2100.

  In addition, including the slit 225 that penetrates the film 220 and the non-penetrating part 226 that is adjacent to the slit 225 in the Y direction formed along the Y direction pulls the first tab 222. This is more effective from the viewpoint of surely connecting all the lid portions 221 and cutting one lid portion 221 when the second tab 223 is pulled.

  Further, the fact that the end on the second tab 223 side of the breaking line 224 is configured by the slit 225 is more effective from the viewpoint of reliably cutting one lid portion 221 when the second tab 223 is pulled. Is.

  In addition, the multi-chamber container 210 further includes a locking portion 250 that is disposed at both ends of the multi-chamber container 210 to lock the support frame 300. This is because the chip 230 is taken out from the container 2100 in a clean state. It is even more effective from the viewpoint of improving convenience.

  Further, the multi-chamber container 210 further has a ridge 212 surrounding each opening 211, and the film 220 adheres to the end surface of the multi-chamber container 210 on the side of the opening 211 and the surface of the ridge 212 to form the opening 211. The sealing is that the adhesion area of the film 220 to the multi-chamber container 210 is increased because the bonding area between the film 220 and the multi-chamber container 210 is expanded as compared with the case where the multi-chamber container 210 does not have the protrusion 212. Is more effective from the viewpoint of increasing

  In addition, the fact that the direction in which the second tab 223 extends is the same as the direction in which the fracture line 224 extends is easy to design with a simple shape, and the degree of freedom in designing the size of the second tab 223 is higher. .

  Further, the film 220 is continuous in the X direction by the non-penetrating portion 226 and seals all the opening portions 211 of the multi-chamber container 210 with one sheet. Therefore, the eight openings 211 of the multi-chamber container 210 are closed at a time. Therefore, in this way, the configuration in which one film 220 closes all eight openings 211 can further increase the productivity of the sealed container 200 compared to the case where the container 2100 is individually closed with a film, Further, the risk of contamination in the production process of the sealed container 200 can be greatly reduced. The above configuration is also advantageous from these viewpoints.

  In the present embodiment, the direction in which the second tab 223 extends and the direction in which the fracture line 224 extends are both the Y direction, but these directions are different as shown in the following embodiments. It may be.

[Embodiment 2]
The sealed container and the sealed container set according to the present embodiment have the same configurations as the sealed container 200 and the sealed container set 100 except that the shape of the film 220 is different. Hereinafter, the same reference numerals are used for the same components as those in the first embodiment, and the description thereof is omitted.

(Constitution)
FIG. 6 is a perspective view of a sealed container 400 according to the second embodiment of the present invention. The sealed container 400 includes a multi-chamber container 210 and a film 420.

  FIG. 7A is a plan view of the film 420, and FIG. 7B is a front view of the film 420.

  The film 420 includes eight lid portions 4211 and 4212 arranged in a row in the X direction, and first tabs 4221 and 4222 that extend further outward in the X direction from the lid portions 4211 and 4212 at both ends in the X direction. It has the 2nd tab 423 extended on the outer side of the W direction from the cover parts 4211 and 4212, and the fracture | rupture line 424 which is a boundary line of the cover parts 4211 and 4212 adjacent to a X direction. The W direction is a direction crossing the X direction. For example, in the present embodiment, the W direction is an oblique direction with respect to the X direction.

  The lid portions 4211 and 4212 are eight regions delimited by a break line 424 formed along the Y direction. The lid part 4211 is seven lid parts other than the lid part 4212, and each of the lid parts 4211 corresponds to each of the seven containers 2100 excluding one container 2100 located at one end in the X direction. The shape of the lid portion 4211 when viewed along the Z direction is a shape (hexagonal shape) in which two corners on one side of the rectangle are cut off obliquely. The lid part 4212 is a lid part located at one end in the X direction of the film 420 and corresponds to the container 2100 located at one end in the X direction. The shape of the lid portion 4212 when viewed along the Z direction is a shape (pentagon) in which one corner of the rectangle is cut off obliquely.

  Each of the lid portions 4211 and 4212 is formed by parting the film 420 by a break line 424 so as to close the opening portions 211 of the containers 2100 arranged in the X direction. The breaking line 424 is formed between the adjacent openings 211 in the X direction and between both ends of the film 420 in the Y direction (see FIG. 7A).

  In the X direction, when the oblique side to which the second tab 423 of the lid portion 4211 is connected is one end and the unconnected side is the other end, the first tab 4221 is located at one end in the X direction of the film 420, The shape of the first tab 4221 when viewed along the Z direction is a pentagon in which one corner of the rectangle is cut off obliquely. The 1st tab 4222 is located in the other end in the X direction of the film 420, and the shape when it sees along the Z direction of the 1st tab 4222 is a rectangle. For example, the length of the first tabs 4221 and 4222 in the X direction is 8.0 mm, and the length (width) of the first tabs 4221 and 4222 in the Y direction is 8.0 mm.

  The second tab 423 protrudes outward in the W direction from the end surface on the opening 211 side of the multi-chamber container 210 and is not bonded to the end surface. The second tab 423 is a rectangular part extending in the W direction from the oblique side of one end side in the X direction of the film 420 of the lid parts 4211 and 4212. That is, the second tab 423 is a second free end that extends further outward in the W direction, which is a direction oblique to the X direction, than the respective opening portions 211. For example, the length of the second tab 423 in the W direction is 8.0 mm, and the width of the second tab 423 (the length in the direction orthogonal to the W direction) is 3.0 mm.

  The fracture line 424 is located between adjacent openings 211 in the X direction. Break line 424 includes a slit 425 and a non-penetrating portion 426. The slit 425 is formed along the Y direction from one end of the oblique side on the second tab 423 side of the lid portions 4211 and 4212. The non-penetrating portion 426 is adjacent to the slit 425 in the Y direction. That is, the direction in which the breaking line 424 extends is different from the direction in which the second tab 423 extends.

  As described above, the breaking line 424 is configured by one slit 425 on the oblique side in the Y direction and one non-penetrating portion 426 on the opposite side to the oblique side in the Y direction. For example, the length of the slit 425 in the Y direction is 5.0 mm, and the length of the non-penetrating portion 426 in the Y direction is 1.0 mm. Further, the non-penetrating portion 426 protrudes from the opening 211 side of the multi-chamber container 210 in the Y direction, and does not contact the end surface of the multi-chamber container 210.

(Function)
When the first tab 4221 or 4222 is pulled along the X direction, the film 420 is continuous in the X direction at the non-penetrating portion 426, and thus peels off from the end surface of the multi-chamber container 210 without breaking. Therefore, all the eight openings 211 of the sealed container 400 are completely opened. It is more preferable to pull the first tab 4221 that does not have the breaking line 424 between the lid part 4212 and the film 420 at the non-penetrating part 426 in the X direction. The method for individually opening the containers 2100 and the method for dividing the sealed container in units of the containers 2100 are the same as those in the first embodiment.

(effect)
In the sealed container 400 according to the present embodiment, since the direction in which the breaking line 424 is formed is different from the direction in which the second tab 423 extends, the opening 211 of the multi-chamber container 210 adjacent to the Y direction. The second tab 423 can be arranged avoiding the above.

  Further, since the second tab 423 extends obliquely in the W direction, that is, in the X direction that is the arrangement direction of the openings 211, the second tab 423 is more effective from the viewpoint of reliably closing the openings 211 with the film 420. Is. This effect is due to the following reason.

  Since the second tab 423 is a free end, the adhesion of the film 420 to the multi-chamber container 210 is poor in the vicinity of the second tab 423 in the lid portions 4211 and 4212 due to, for example, turning over when the film 420 is adhered. May occur.

  On the other hand, in order to make the position of the opening 211 in the sealed container set 100 correspond to the position of the well of the 96-well microplate, the X direction between the openings 211 of the multi-chamber container 210 or from the opening 211 to the outer wall surface is used. And the dimensions in the Y direction are limited. For this reason, the dimension is small. Therefore, the contact area of the film 420 with the multi-chamber container 210 in the X direction and the Y direction is also small. On the other hand, when the size of the portion other than the X direction and the Y direction (the portion in the W direction) on the end surface to which the film 420 of the multi-chamber container 210 adheres is increased, the contact area of the film 420 with the multi-chamber container 210 may be increased. Is possible.

  When the contact area is larger, the above-described adhesion failure of the film 420 is further suppressed. From the above, it is more effective that the extending direction of the second tab 423 is the W direction from the viewpoint of reliably sealing the opening 211 with the film 420.

  The second tab 423 is pulled in the Y direction after being pulled in the W direction or the Y direction, for example, in the W direction. Then, since the slit 425 is formed from the oblique side of the lid portions 4211 and 4212 to a portion other than the non-penetrating portion 426 in the Y direction of the film 420, the corresponding lid portions 4211 and 4212 are extended to the non-penetrating portion 426. Peel off. In this manner, the opening 211 is completely opened by peeling the lid portions 4211 and 4212 within the range of the slit 425. The non-penetrating portion 426 is torn off after the opening 211 is completely opened. Therefore, the film 420 is more effective from the viewpoint of reliably breaking the film 420 at the breaking line 424 when the containers 2100 are individually opened.

  Further, since the non-penetrating portion 426 is not bonded to the multi-chamber container 210, it is more easily broken. Therefore, the breaking line 424 is more effective from the viewpoint of reliably breaking the film 420 when the containers 2100 are individually opened.

  The sealed container 400 further exhibits the effects of the first embodiment described above other than the effects described above due to the extension direction of the second tab being the same as the extension direction of the fracture line.

[Modification]
Furthermore, the embodiment of the present invention may include further modifications as long as the effects of the present invention are obtained.

  For example, as shown in FIG. 8, the multi-chamber container 510 does not have the above-described protrusions, and the film 220 has an end surface on the opening 211 side in the multi-chamber container 510 and the opening 211 in the inner peripheral wall of the container 5100. The opening 211 may be sealed by bonding to the end on the side. The length in the Z direction of the portion of the film 220 bonded to the end on the opening 211 side in the inner peripheral wall of the container 5100 (that is, the Z from the opening 211 of the portion of the inner peripheral wall to which the film 220 is bonded) The distance in the direction is d) in FIG. For example, when the film 220 is heat-sealed, the film 220 is pressed with an appropriate force toward the multi-chamber container 510 with a heat-resistant elastic body such as an elastic body made of silicone rubber, as described above. Can be adhered to the multi-chamber container 510.

  As described above, by adhering the film 220 to the end of the inner peripheral wall of the container 5100, the film 220 can be applied to the multi-chamber container 510 with a sufficient adhesion area even in the multi-chamber container 510 having no protrusions. It becomes possible to adhere. Thus, the film 220 is adhered to the end surface on the opening 211 side in the multi-chamber container 510 and the end on the opening 211 side in the inner peripheral wall of the container 5100 to seal the opening 211. This is even more effective from the viewpoint of increasing the adhesive strength of the film 220 to the multi-chamber container 510.

  In the multi-chamber container 210 having the ridge 212, the film 220 is passed from the end surface on the opening 211 side of the multi-chamber container 210 to the end on the opening 211 side of the inner peripheral wall of the container 2100 through the surface of the ridge 212. It may be glued. Adhering the film 220 to the multi-chamber container 210 in this way is even more effective from the viewpoint of increasing the adhesive strength of the film 220 to the multi-chamber container 510.

  The containers 2100 and 5100 may be empty. Even if the containers 2100 and 5100 are empty, the opened containers 2100 and 5100 can be used as endotoxin-free clean containers or instruments.

  Moreover, the latching | locking part shown by FIG. 9A is comprised by the square-column-shaped protrusion part 551 which protrudes in a X direction. Further, the support frame 600 shown in FIGS. 9B and 9C has a recess 610 cut out in a square column shape at one end of the inner wall surface of the support frame 600. The protrusion 551 is fitted in the recess 610. As described above, various forms such as a form in which the rod is inserted into the hole and a form in which the convex part fits into the concave part can be adopted for locking the closed container to the support frame.

  Further, for example, in the embodiment of the present invention, the package object may not be the chip 230 but may be a liquid. The support frame may be bottomed or may further have a lid. The first tab may be disposed only on one end side in the X direction. The second tab may be disposed at both ends of the lid portion in the Y direction, or may be alternately disposed at one end and the other end of the lid portion in the Y direction. Further, the shape of the breaking line may be a straight line or a non-straight line including a curved portion.

  The airtight container which concerns on this invention can take out the to-be-packaged object accommodated in the container in the clean state from a container with the clean state. The closed container and the closed container set according to the present invention are applied to a technical field in which contamination with endotoxin is not allowed, such as medical examinations, experiments, and pharmaceutical preparations, and can contribute to further development of the technical field. Be expected.
